Head mojo 94 mounting for tele

post #1 of 9
Thread Starter 

 Anyone have any suggestions on this.  Been searching for what ever info I can find and most use this ski for alpine.  Will be mounting with BD o1's.....Thanks

Depends on what you want and how you ski.  

 

As a rule of thumb, I typically mount alpine skis for tele so that the boot center (measured from middle of pinholes to the end of the heel) is -1 cm to -2 cm, behind the alpine boot center mark of the ski.  Mostly softer snow=back, harder snow=forward.  

 

If you intend to ski almost all hardpack and/or like a real turny ski and/or parallel most of the time, maybe boot center on the alpine center mark or even +1 cm forward.  Faster straightlining benefits from more rearward.  

 

Edit: Just saw your x-post on TTips.  Be interesting to see what people there say.  Are you sure there's no alpine boot center mark?  That'd be weird.  If so, then I'd go pins on chord center, minus any twin tip on the tail, or ball of foot on center of running surface.

Phil - if it makes you feel any better, I'm going to mount my P3's at -1 or -2 from boot center.  That will probably translate to slightly forward of where your Akomas were mounted.

It might if you can ski them before I mount mine up   ...... I think there is a big enough pile of sand/dirt off 494 and lyndale if you really wanted to try.  Maybe if the pile is still there this winter I might have to hike to the top and see what happens.  Might be a longer run than Buck Bump

There is a mark on the side of the ski.  So if i measure from the

 

-tip of the ski to the mark we have 40 3/16"

- tip to tip is 73" so middle of the ski would be 36 1/2"

- If I line my 3 pin of my boot up with the mark 36 1/2" that seems to put the ball of my foot right on or close to the original mark on the ski.

 

So how to you figure out were  on your boot your ball of your foot is.  The boots I have do not have a mark on them( Energy's) but I have heard of other boots having this mark.

 

I had a pair of Akomas that I also did the same measuring on I believe and per Movements recommendations and many others I had those mounted +2.  The ski was great on hard pack and softer snow due to sun melt but out west it did not feel right to me.  So from what I am understanding Bob is that those might have been mounted to far forward for my liking or for that kind of condition(left over snow and some powder)?  I do like to turn and carve hard but those were 92 in the waist. I picked them up for a ski to bring out west when I would go.

Don't overthink this - all those measurements you cited were confusing, and kind of irrelevant.  From what you're saying, I'd mount the skis so that the boot midsole is 1.5 or 2 cm behind the mark on the side of the ski, assuming you tele turn most of the time.  If you parallel a lot, consider -.5cm or right on the line.  Ignore the pin line for that method of locating the mount.  

 

The ball of foot is usually designated as the point at the back of the bellows on the side of the boot...which is confusing, I know.  It's easier to point it out than describe it on the interwebs.  But for you I'd still go with voodooing the boot midsole to the midsole mark on the ski method.  

 

Drink some beer.  Mark the midsole of the boot per the directions I described in my first reply, then put the boot in the binding and align the boot+binding over the mark on the side of the ski according to the voodoo described above (say -1.5 from the line).  Use a grease pencil to mark the location of the binding.  Remove the boot, drink some beer, relocate the binding on the ski according to you marks and use the grease pencil to mark the location of the screw holes.  Then use the jig to insure the holes are centered and straight based on where you marked them and after drinking a beer, put some holes in your skis.  

 

Or set your skis on the floor and mark the point where the back twin tip leaves the floor.  Measure from the tip to that point.  Divide that by 1/2 to locate chord center and put the pin line on that.  

 

You can do both methods to compare locations, but I'd favor the boot center 1.5 to 2 cm behind the midsole mark on the ski method.

Phil - Your Akomas were not +2.  I was using them to figure out some other stuff, and if the mark on the skis represent boot center, they are behind boot center quite a bit.  They also have GIANT tips & tails - I wouldn't use those as a reference for mounting, although they do ski quite nicely.

So where are my akomas mounted at then.  When I gave them to the guy at REI I had measured from tip to tall.  Found the middle and made a mark from there that was +2. Thats what Movement told me to do as well.   I'm sure all this is not as hard as it seems but for me it's not making since.  I will try and read what on TTips about mounting as well and see if that makes any since to me.  Thanks for the help Bob and Axebiker

Sounds like REI did +2 from chord center then, not midsole.  There was a midsole mark on your Akomas, which is what I was using to measure for the sake of mounting up twins.
